Thank you for the suggestion. Unfortunately I cannot get past an 'Attribute Error' on ___GetItem___. If the arguement of restricted traverse is a quoted string as in your example, it works. What I need to pass is a variable that contains that string and have it rendered. For example, your suggested: <dtml-with "restrictedTraverse('folder/subfolder/myimage.jpg')"> <dtml-var title_or_id>: <dtml-var height>, <dtml-var width> </dtml-with> works, but With request setting QUERY_STRING = "myimage.jpg" <dtml-let "MyImage='folder/subfolder/'+QUERY_STRING") <dtml-with "restrictedTraverse(MyImage)"> <dtml-var title_or_id>: <dtml-var height>, <dtml-var width> </dtml-with> </dtml-let> generates the attribute error on GetItem Any ideas?

In a DTML method, a string is constructed in a variable that is the relative URL of an Image. For example ... <dtml-let MyImageId="'folder/subfolder/myimage.jpg'">
using <dtml-var MyImageId> results in just the string being returned a hand constructed image tag like <img src=<dtml-var MyImageID> alt=""> will render the desired image, but does not provide access to its 'Image object' attributes like height and width.
Hi, you can get every object via an url with restrictedTraverse. Then you can access the properties of the object... Example: <dtml-with "restrictedTraverse('folder/subfolder/myimage.jpg')"> <dtml-var title_or_id>: <dtml-var height>, <dtml-var width> </dtml-with> Cheers, Maik
